Answer 1

Answer:

(i) 3 : 10

(ii) 1 : 4

(iii) 3 : 5

Step-by-step explanation:

(i) 3m = 300 cm

ratio = 90 : 300 => 9 : 30 => 3 : 10

(ii) 1 kg = 1000 g

ratio = 250 : 1000 => 25 : 100 => 1 : 4

(iii) 36 months is 36/12 years = 3 years

HERE'S YOUR ANSWER !!

______________________________

Since, the quantities of the following are not same in each question, we will first make their quantities same.


_______________________________

a ) 90 cm to 3 m

Changing m to cm

3m × 100 cm = 300 cm

{ 1 m = 100 cm }

=> 90 cm to 300 cm

=> 90 : 300

=> 90/300

=> 3/10

=> 3 : 10 ANS


______________________________

b ) 250 g to 1 kg

Changing kg into g

1 kg × 1000 g = 1000 g

=> 250 g to 1000 g

=> 250 : 1000

=> 250/1000

=> 1/4

=> 1 : 4 ANS


_____________________________

c ) 36 months to 5 years

Changing year into months

5 × 12 = 60 months

{ 1 year = 12 months }

=> 36 months to 60 months

=> 36 : 60

=> 36/60

=> 3/5

=> 3 : 5 ANS
